Desert gardening in Gilbert, AZ demands a unique approach — especially when it comes to fertilizing. The key to success is giving your plants the nutrients they need without disrupting their natural drought resistance. This guide will walk you through everything from product selection to application timing so your yard can thrive in the heat.

Know Your Soil
Gilbert’s soil ranges from sandy to compacted clay, both of which make water and nutrient retention difficult. Before fertilizing, it’s important to know what you’re working with. A quick soil test kit can reveal your pH and nutrient deficiencies — giving you a better idea of what your plants really need.
What Type of Fertilizer is Best?
For desert-adapted plants, use a low-nitrogen, slow-release fertilizer or an organic blend with balanced NPK. Avoid high-nitrogen formulas which promote weak, lush growth that doesn’t handle heat well.
- Succulents & Cacti: Use a cactus-specific fertilizer with micronutrients.
- Native Shrubs & Flowers: Balanced 5-5-5 or 8-8-8 mixes work well.
- Desert Trees: Apply tree spikes or deep-root liquid feed once per year in early spring.
When to Fertilize in Gilbert
Apply fertilizer during the cooler growing seasons — early spring (March–April) and fall (October). Avoid summer fertilizing, as it can stress plants already coping with extreme temperatures.
Smart Application Tips
- Apply fertilizer near the root zone, not directly on the stem or trunk.
- Water thoroughly after application to help nutrients absorb.
- Avoid applying just before heavy rain to prevent runoff and waste.
Common Mistakes to Avoid
- Over-fertilizing: This can burn roots and disrupt natural resilience.
- Using lawn fertilizer: It’s too strong and not balanced for desert plants.
- Ignoring plant needs: Some established natives may not need any fertilization at all.
Let Your Landscape Thrive
